Yes, Cervical Dystonia is a rare neurological disorder that originates in the brain. 

Most cases of isolated Cervical Dystonia do not have an underlying identifiable cause or trigger.

However, Cervical Dystonia in some cases is considered secondary.

The condition Cervical Dystonia occurs as a consequence of another disorder or disease.

An example of underlying Cervical Dystonia diseases would be spasticity, Ataxia, or Parkinson's Disease. 

The NORD Organization states symptoms of cervical dystonia may begin slowly and can involve any of the muscles of the neck.

The head posture in cervical dystonia can vary. The most common abnormal posture associated with cervical dystonia is the twisting of the chin toward a shoulder so that the head rotates sideways (torticollis).

Other abnormal postures include:

• anterocollis, in which the head tips forward
• retrocollis, in which the head is tilted backward
• laterocollis, in which the head tilts toward one side.

Symptoms of cervical dystonia vary over the course of the disorder.

Stress and/ or excitement can cause Cervical Dystonia symptoms to temporary worsen. 

People with dystonia often complain of pain and exhaustion because of the constant muscle contractions.

If dystonia symptoms occur in childhood, they generally appear first in the foot or hand.

There is no cure for Cervical Dystonia. 

Botox is usually the first treatment for Cervical Dystonia. 

Botulinum toxin injections aka Botox are the treatment of choice for focal dystonia, which is the neck and head in cervical dystonia.

Botulinum toxin is a neurotoxin that is injected into the dystonic neck muscles in small doses. 

Small amounts of Botox are injected into affected muscles. The Botox helps to prevent muscle contractions and can provide temporary improvement in the abnormal postures and movements that characterize dystonia.

The Botox decreases muscle spasms by blocking release of the neurotransmitter acetylcholine.

The effect of Botox is typically is seen a few days after the injections.

The results of Botox treatment can last for several months. The outcome of Botox treatment will vary among individuals.

Several classes of drugs that affect different neurotransmitters may be effective for various forms of dystonia.

These medications are used “off-label". 

The use of the term "off-label" means the medications are approved by the U.S. Food and Drug Administration (FDA) to treat different disorders or conditions but have not been specifically approved to treat dystonia. 

The response to these "off-label" medications vary from each individual. 

The following are "off-label medications to treat Cervical Dystonia:

Anticholinergic agents block the effects of the neurotransmitter acetylcholine.

Drugs in this group include trihexyphenidyl and benztropine.

Sometimes these medications can be sedating or cause difficulties with memory, especially at higher dosages and in older individuals. 

Other side effects such as dry mouth and constipation can usually be managed with dietary changes or other medications.

GABAergic agents are drugs that regulate the neurotransmitter GABA. T

Gabaergic medications include the benzodiazepines such as diazepam, lorazepam, clonazepam, and baclofen.

A common side effect of Gabaergic is drowsiness.

Dopaminergic agents act on the dopamine system and the neurotransmitter dopamine, which helps control muscle movement. 

Side effects from Dopaminergic agents such as weight gain, depression, and involuntary and repetitive muscle movements can restrict the use of this medication.

MY STORY WITH CERVICAL DYSTONIA

There must be rocks in my neck and shoulder I convey to the pain specialist, Dr. Hamid Fadavi.

Dr. Fadavi tells me he has reviewed my hospital CT and X-Rays of my neck and he does not believe I have arthritis.

The doctor also notes several blurry areas on my CT.

I ask if I do not have arthritis is the Relapsing Polychondritis the cause of my neck pain?

Also, can the inflammation from Relapsing Polychondritis causes the blurriness on my X-Rays?

Dr. Fadavi does not answer me immediately.
Instead, I find him looking intensely at my face, neck and then he asks me to stand against his office wall.

As I stand against the wall, Dr. Fadavi measures the distance of my shoulders and stance.

After Dr. Fadavi has my measurements he advises me to sit back in my chair.

Before I sit back in my seat, I anxiously rattle out my additional symptoms to Dr. Fadavi.

I proceed to tell him that it sounds crazy, but my face looks distorted.

I have noticed that my face is crooked.
Dr. Fadavi does not think my symptoms are crazy.

The doctor asks me for my driver's license.

I give Dr. Fadavi my driver's license and show him a video I sent to a friend a day earlier.

It is apparent in the video that my jawline is pulling and jerking involuntarily.

The doctor examines the trigger points in my body.

He asks me numerous questions. Is my neck pain better or worse in the morning?

I answer the pain is better in the morning. The pain increases as the day proceeds.

Dr. Fadavi tells me he believes I have Cervical Dystonia.

Oh, what is Cervical Dystonia?, I ask.

Dr. Fadavi patiently informs me about Cervical Dystonia and the Botox treatment plan for Cervical Dystonia.

I ask is there a lab test to confirm Cervical Dystonia? No, say Dr. Fadavi. You have to go by the patient's symptoms.

So, how bad are my Cervical Dystonia symptoms? Moderate, the doctor, replies.

Doctor Fadavi then ask me for my phone. He tells me he is going to take a couple of photo of my face and then compare the photos to after treatment.

The doctor shows me the pictures. My face does look crooked.

The photos show how muscles are pulling and spasming in my neck region.

I then ask, does the Botox treatment work?

Sometimes and the results vary, explains the doctor.

My hope for an instant cure has quickly diminished.

I then ask the doctor, what causes Cervical Dystonia?

The doctor answers, the medical community, is not sure what causes Cervical Dystonia.

Cervical Dystonia is a rare disease that usually occurs in middle age people, forties, fifties.

Ugh, Really?!, You can't make these stories up, screams inside my head.

My body already battles with the rare diseases of Sheehan's Syndrome, and Relapsing Polychondritis. I am not seeking another rare disease.

The kind-hearted doctor tells me to schedule with the front desk for Cervical Dystonia Botox treatment.

Hopefully, the Botox will stop my muscles from spasming.
